Platform
Features & SDKs
One platform. Every runtime. Evaluate feature flags locally with O(1) reads, synchronize changes in real time, and stay resilient during outages.
Why SOASAP SDKs
O(1) Local Evaluation
Every flag is evaluated locally from an in-memory snapshot. No network calls, no disk access, and no latency on the hot path.
Real-Time Synchronization
Server-Sent Events propagate flag changes to every connected SDK instance within milliseconds.
Instant Cold Starts
Persistent local cache restores the latest snapshot immediately, even before the first network connection succeeds.
Offline-First Resiliency
Applications continue serving feature flags during outages using the last known snapshot.
Non-Blocking Startup
Background synchronization starts asynchronously and never delays application startup.
Production Safety
Built-in safeguards prevent malformed payloads, memory abuse, and synchronization failures from impacting your application.
SDK Ecosystem
Production-ready SDKs with a shared architecture, local-first evaluation, persistent caching, and real-time synchronization.
Coming Soon
One Architecture. Every Runtime.
The same core capabilities ship in every production SDK — local evaluation, live synchronization, durable cache, and offline resilience.
